ROTOR OF MAGNETIC ANGLE DETECTOR, MANUFACTURING METHOD OF THE SAME, AND MAGNETIC DETECTOR INCLUDING ROTOR

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method for accurately manufacturing a rotor of a magnetic angle detector without causing burrs, a rotor manufactured by the manufacturing method, and a magnetic detector including the rotor.SOLUTION: Tooth tip surfaces and tooth surfaces of teeth to be formed on a rotor 10 are simultaneously ground with a single grinding stone 12. The grinding stone 12 includes tooth tip grinding section (face) 18 for grinding the tooth tip surfaces 16 of the teeth to be formed on the rotor 10, and a tooth surface grinding section (face) 22 for grinding the tooth surfaces 20 of the teeth. The grinding stone 12 is configured to simultaneously grind the tooth tip surfaces 16 and the tooth surfaces 20, with a rotation grinding operation around an axial line 14.
